Careful planning of operations is critical to success of the closed reduction and internal fixation (CRIF) surgery to fix proximal femur fractures. This paper presents a novel surgery planning simulation for the CRIF. The developed simulation employs 3D femur model reconstructed from actual patient’s CT data, and enables the user to make a plan on the model using 2D mouse. A projection scheme i...

Complex maxillofacial deformations continue to present challenges in analysis, planning and correction beyond modern technology. The purpose of this paper is to present a virtual reality environment for surgeons to perform virtual orthognathic surgical planning in three dimensions. A surgical planning system, “PC-based virtual reality surgical simulation for orthognathic surgery” (VRSSOS), cons...

UNLABELLED The objective of this pilot project was to devise a new image acquisition and processing technique to produce PET/CT images rendered in 3-dimensional (3D) volume that can then be reviewed in several 3D formats such as virtual bronchoscopy and colonoscopy "fly-throughs" and external "fly-arounds." METHODS We tested the new imaging and processing protocol on 24 patients with various ...

Many medical departments use several multi-disciplinary technologies to support the planning of the surgery. For complex operations a collaboration between different experts can improve the success rate, but the tools are mostly on-premises software and limit the good cooperation. In this case, the orthognathic and dental surgery uses 3D and CT scans to plan the surgery beforehand by making use...

BACKGROUND To discuss the role of Liver 3D printing in the treatment of complex massive hepatocarcinoma with rare variations of portal vein. METHODS Data of enhanced computed tomography (CT) were imported into the medical image three-dimensional visualization system (MI-3DVS) to create Standard Template Library (STL) files, which were read by 3D printer to construct life-size 3D physical live...

Introduction: Sensorineural hearing loss (SNHL) is one of the possible complications of radiotherapy treatment of brain tumors. The auditory system of patients with brain tumors often is placed inside of radiation field and receives a significant amount of radiation dose resulting in hearing loss. The purpose of this study was to compare contouring and delivery dose to cochlea...

External beam radiation therapy (EBRT) is an effective and widely accepted form of treatment for many types of cancer that requires extensive planning. Unfortunately, current treatment planning systems have limited or no available visual aid that combines patient volumetric models extracted from patient specific CT data with the treatment device in an inclusive 3D interactive simulation. We are...

introduction: the complex geometry of breast and also lung and heart inhomogeneities near the planning target volume (ptv) result in perturbations in dose distribution. this problem can result in overdosage or underdosage in the match region of the three treatment fields. the purpose of this study is to create a homogeneous dose distribution in the match region between the supraclavicular and t...

Introduction: The functionality and quality of any treatment planning system (TPS) strongly depends on the type of Algorithm which is used by it. Obviously, the role of dose distribution algorithms in calculation of prescribed dose inside the tumor in modern radiotherapy techniques has more important than past to achieve the best clinical outcomes, especially in tumors which ar...
